Hi. I have aquired this as a tanka from Jaipur, but I could not find a match for it in Krause.
I would appreciate your help.

Thank you Amit!
Do I read correct that the year marked is 47?
The closest match that I could find is the takka of Ratan Singh ( AH1244-1268) but the regnal year, which should be of Shah Alam II, is only listed as 41 in Krause

Yes. The date is indeed RY 47.
KM should be used as a reference for types. In case of IPS, I find that quire a few verities  and most dates are not listed. My view is that back in the early days, copper coins, which traded as a commodity were not researched in details which has resulted in these coins not being listed.
